Our mission to help improve the climate looks incredibly promising. As we grow, so does our ability to contribute more substantially to a world full of environmentally friendly, intelligent and energy-efficient solutions for indoor climate comfort.
The potential for our mission is excellent, considering all the properties that do not yet have our type of solutions but instead use fossil fuel solutions.
In the Netherlands, the government has adopted a green agenda whose vision is to convert to fossil-free heating and cooking (gas stoves). This means that the country’s national gas network should be fully phased out by 2050.
Development to achieve climate goals
Sustainability is an important factor throughout a product’s life cycle. Proactive market-based product development has several target criteria. Our products must be resource-efficient in both production and operation to help reduce climate impact.
How much energy do you save with a heat pump?
The total energy requirement for heating a medium-sized house including hot water is 24,200 kWh per year. A heat pump with a SCOP value of 5 reduces energy consumption by 19,360 kWh or 80%, compared to direct-acting electricity. With a heat pump, the total energy consumption instead becomes 4,840 kWh.
A step has already been taken
Gas is to be completely phased out within 35 years, which means that today all seven million homes will require a different solution. A step has already been taken by abolishing the requirement that newly built houses must have gas as the energy source for heating and cooking. A plan has also been proposed to gradually disconnect homes that are presently connected to the gas grid as from 2021.
Meeting the demand for energy savings
Heat pumps are a vital part of the solution and installations of NIBE’s air/water heat pump range has increased significantly. The reasons for their popularity are obvious. With a seasonal coefficient of performance (SCOP) value above 5.0, a heat pump delivers more than five times the heat per year compared with an electric cartridge heater with the same energy consumption. In addition, it provides optimal savings as the heat pump automatically adjusts to the home’s power needs year-round.
Kortenoord district of Wageningen, The Netherlands
A new and innovative housing project that takes a sustainable approach is under way, and roughly 1,000 homes are being built without a gas pipeline. The houses have optimum insulation and are equipped with new energy-saving products such as heat pumps, solar panels and solar water heaters.
Increase energy efficiency and lower operating costs
In 2017 the company decided to increase energy efficiency in one of its industrial properties, which houses an auto workshop and vehicle inspection centre, to lower operating costs and cut the pipes to the district heating system. Klövern chose to test a completely new combination based on five 20 kW air/water heat pumps and solar panels with the capacity to generate 24,000 kWh per year.
It’s impressive how good the heat pumps have become
“Previously we bought 253,000 kWh of district heating annually, and with NIBE’s heat pumps we only need to use 73,000 kWh of electricity per year. Since we generate 24,000 kWh of solar energy, we only need to buy about 49,000 kWh. It’s great, and we expect to get a return on our entire investment in about seven years. It’s impressive how good air and water heat pumps have become, and nowadays they seem as efficient as geothermal heating and very reliable."
More projects in the future
That we have been able to achieve fantastic overall cost efficiency with substantial support from solar makes the costing very attractive, and I look forward to more projects like this in our property portfolio,” says Tobias Ljungkvist, operating technician at property company Klövern.
The cold is a challenge
The electric vehicle trend is facing fresh challenges. One of them is the cold, which can cause batteries to lose capacity or stop working and thus limit the vehicle’s range.
Intelligent electronic control
At the request of Scania, which has developed a new electric bus, Backer has produced a solution that heats battery packs with integrated circuit boards that are easy to install in the vehicle assembly. Intelligent electronic control keeps the battery pack at the correct temperature, and the bus passengers arrive at their destination not only sustainably but safely.
If your electricity is cut off during the cold season, your home will quickly chill down. Most important is to have water, food and heat and to be able to receive information from the authorities and media. Households that have wood-burning stoves can keep the house warm and comfortable.
Gather everyone in a room, hang blankets over the windows, cover the floor with rugs and build a tent over a table to keep in the heat. Consider fire hazards. Turn off all the lights and alternative heat sources before you go to sleep. Let fresh air in regularly to get oxygen.
To ensure correct overhaul and maintenance of wind turbines and their blades and to reduce maintenance stoppage times, we have found a solution that permits the blades to remain warm during the repair period.
Central intelligent control
The concept is based on a central intelligent control that is combined with heating jackets. The unit controls the temperature via sensors in the heating jackets. At the same time, it also measures and logs the ambient temperature and humidity.
All management and control of temperature, data, alarms, trend curves and programme planning time is via a touch-screen panel.
The Blue Point system is a system for heating railway gear so it can be kept snow and ice free. The system accounts for the relationship between precipitation, temperature and wind to control the heating.
Built-in weather forecasts
The system receives a weather forecast every hour for the next 1-3 hour interval. This means a local and accurate forecast for snow and frost. This feature can mean energy savings of up to 40%. The system also has built-in alarms, information on energy consumption, forced heating and more.
On a continent with much harsher winters than in Europe, apart from northern Scandinavia, a wood-burning stove is an important heat source for many people. For example, 350,000 households or 35% of non-urban households in the Canadian province of Ontario use wood as a heat source some or all of the time.
The difference between the continents can be understood best by comparing the product descriptions for some of Canadian company Regency’s products with that for one of NIBE Stoves’ bestsellers in the Nordic region, Contura 500. Regency’s stove sizes are given based on room size and using the BTU, British Thermal Unit, as a measure of output.
As they say in Canada, you light the fire in October and it burns until April.
Regency® Pro-Series F5100 Wood Stove, 80,000 BTU = 23 kW. You can now insert a 55 cm log, and a 40 kg load produces a burn time of up to 30 hours!
Nordiska Contura 500 has an output of 5 kW, can take 33 cm logs and has a burn time of 1-2 hours.
An article in the Toronto Star reflects the role of wood-burning stoves well:
“It’s the end of the working week and you still have a long walk home in the dark, with the wind throwing hard snowflakes, like pellets, in your face. But once home you can relax. With a cup of tea or a glass of wine and the ultimate in winter comfort, a log in a wood-burning stove.”
